tating., additionall or'special. operations on thel part of the operator.V Y

In the drawings, the 'locking means formingrthe object of this invention is shown applied vto a dump carhaving a body 1 and dumping doors 2. operating the doors -Visthe door operating mechanism shown in Patent No. 1,321,928, Lindstronnet al., November 18, 1919,and comprises links 1 pivotally connected tothe ends vof the doors 2 and to yokes 5 which are' pivotally supported on Vpins G carriedby crank framesy 8. The, crank frames 8 are pivotally mounted on the center sills 10 and are operated by the shafts 11 and 12 Which are `connected to the crank frames. 8 by means of the safety clutches 14 which permit of the doors dropping quicklyl without danger to the operator.v rIlhe'outer ends `of the shafts 11l and Y12V are j'o'urnaled in aside sill 16 and the shafts have the segmental gears 1'? and 18, respectively, keyedthereon adjacent the side sill 16.` To operate the shafts 11 anjd 12 there isplovidedashaft 20 joiirnaled in brackets r22- mounted on the side sills 16 and in a bracket-21. mount-edonthe longitudinal member 1.9, and havingsquared ends23A projecting beyondV the brackets to receive an The means shovvnrfor4 andclosing the` doorsgand Without necessi-` operatingwvrench. Between' bracket 21 and the adjacentgbracket 212, the sha-ft 20. has keyed thereon a pinionf21which meshes with the segmental gear 18'and a rackvportion 25 of a longitudinally movable rack membe'ri26 which is guided bythe brackets 27 and 28 and is -provided with a second rack portion 29 adjusta-biy `mounted thereon and meshing With the segmental gear I1i'.

The rack emeinber is also provided with a-'notched portion' 30 which canA be eng-aged byapawl 32 carried on a shaft 33 journaled on the lbrackets `22-and 21'and having` operating handles 34; at itsends. In this construction in v order to provide a mechanism which can `be readily operated to Vdrop the doors when the cargis loaded it has beenv found necessary to reduce to a Aminimuinthe amount that thevr crank frames S-inove' past their dead'centers in Orderto lock the doors .in theQfully .closed position. Reducingthe distance fthe 'crankl frames jmovef'past their dea dcentersrednces theirtendency to remainngthe `locked position andI renders car body 1 Aa lockingV pawl 40 fixed on a" shaft 41 which is journaled in a bearing bracket y42 secured to the end slope sheet 43@ and in the bracket 44 mounted on the longitudinal member 19. Adjacent' the bracket4` 44 the shaft 41 is provided with a lever arm 45 having its outer endpivotally connected to one end of a rod 46avliich is adjustable as to its length and has its other end pivotally connectedA to the outer end of a lever 47 which is fnlcrumed on a bracket 48 mounted on the slope sheet 43. The lever arm 45 is also pivotally connected to one end of a rod 5() which'is adjustable'as to its length and has its other end Vpivotally connected to the outer end of a curved weighted lever arm 51 fixed to a shaft 52vjournaled in the bracket 21 and in a bracket carried by the slope sheet 54. Fixed on the shaft 52 is a looking pawl 55, both the pawl 55 and the pawl 40 being provided with projections which, when the pawls are in locking` position, engage beneath the lugs 56 formed on the yokes 5.

With the doorsin the fully closed position, the operation of dropping the doors will be the same as described in Patent No. 1,321,928, the pinion 24 being operated by shaft 2O torotate theshafts 11 and 12 through its engagement with lthe rack member 26 and segmental gear 18,v respectively, the shafts being rotated until the lugs 60 and 61 of the safety clutches 14 engage to transmit motion to the crank frames 8 to drop the doors. Vith the locking means ap.- plied as shown in the drawing and considering it in the locking position' when the doors are fully closed, thel movement of the rack member 26 during the taking up of the lost niotion'in the safety clutches 14 will bring the inwardlyprojecting finger' 65 on the rack member 26 into engagement with the lever 47 and shift'the lever 47 to operate the locking pawls 40 and 55 and withdraw them from engagement with the lugs 56 on the yokes 5, the rod 46 being of such length that the pawls 40 and 55* are withdrawn before the crank frames 8 are operated to drop the doorsand the weightedlever 51 being of such shape that the weighted portion 7() tends,A to lholdfthe locking pawlsin the releasey position when the rack member 26 has made its full movement.

When the pinion 24 is operated to rraise the doors the segmental gear 18 and rack member 26 are operated, withdrawing the finger-65 from the lever 47 and rotating the shaftsV 11 and 12'nntil the lost 'motionI in the safety-clutches 14 is takenl up and the crank frames 8 are operated to raise the doors. As the shaftll is rotated, raising'V the crank frame 8 and the yoke 5 connected thereto, a projection 71 on the yoke 5 en-j` gages with a projection 72 on the Vlocking "5 as the doors are moved to the fully closed position.
